Make good use of "$:/core/modules/utils/base64-utf8/base64-utf8.module.js"
* Add a new base64Encode()
* Both of base64Encode and base64Decode work for Nodejs and Browsers
* add PaletteManager
* add hint for "external" palette-names
* macro utility, for local \import only
this tiddler is never meant to be tagged $:/tags/Macro
contains only a colour macro which allows to call `<<colour "...">>` within a tiddler and get the parameter-name instead of the resolved color
used in the PaletteManager to reveal the original color below the color that just uses its color with the colour macrocall
example:
```
\define get-real-index(string)
\import $:/core/macros/utils
<$wikify $name="result" text="""$string$"""> <- does the "colour" macrocall, but the one that returns the parameter name
<<result>>
</$wikify>
\end
<$set name="color" value={{{ [{$:/palette}getindex[color-of-interest]] }}}>
-> <<colour primary>>
<$wikify name="real-color-index" text="""<$macrocall $name="get-real-index" string=<<color>>/>""">
<<real-color-index>> -> primary
...
```
* transclude PaletteManager in snippets/paletteeditor
* transclude PaletteManager in core/ui/ControlPanel/Palette
* Update ControlPanel.multids
* add style for color inputs in PaletteManager
* Update PaletteManager.tid
* Update PaletteManager.tid
* add tooltips & aria-labels
* Update ControlPanel.multids
* Update PaletteManager.tid
* Update PaletteManager.tid
* Update PaletteManager.tid
* add escapecss filter
this filter would allow creating valid css classes from titles containing special characters
we assign a class to an element using `encodeuricomponent[]` so that the class name is encoded
in a stylesheet we create the classname by `<title>escapecss[]` which applies the uri encoding and escapes characters that need to be escaped
* Update encodings.js
* refactor tagToCssSelector, add escapeCssSelector
* use escapeCssSelector
* escape using CSS.escape if it's available
* Update encodings.js
* revert factoring out escapeCssSelector
... this makes the animation when inserting tiddlers / navigating to tiddlers in the pop storyview less jumpy
it simply sets `overflow-x` to `hidden` for the time of the insert-animation
* First pass at modular wiki indexes
An exploratory experiment
* Fix tests
* Faster checking for existence of index methods
We don't really need to check the type
* Use the index for the has operator
* Fix typo
* Move iterator index methods into indexer modules
Now boot.js doesn't know the core indexers
* Fix up the other iterator index functions
* Fix crash with missing index branch
* Limit the field indexer to values less than 128 characters
* Fallback to the old manual scan if the index method returns null
* Sadly, we can no longe re-use the field indexer to accelerate the `has` operator, because the index now omits tiddlers that have field values longer than the limit
Still need to make the index configuration exposed somehow
* Rearrange tests so that we can test with and without indexers
We also need to expose the list of enabled indexers as a config option
* Test the field indexer with different length fields
So that we test the indexed and non-indexed codepaths
It turns out that the `localeCompare` function used by `compareStateText()` is very, very slow. Replacing it with a straightforward equality test makes one of my test rigs be 10x faster...
Note that this PR reverts the behaviour of match/nomatch to that before #3157. That change was not backwards compatible in that the switch to localeCompare meant that é === e, now it doesn't again.
Approximtely 50% speed improvement in tests opening a storyview with 8,000 entries.
(I've deferred the indentation adjustments until the next commit so that the git diffs are clearer)
